The typical family of four can use 400 gallons of water every day. On average, approximately 70 percent of that water is used indoors.

The typical household retrofitted with water-efficient fixtures and appliances can save 30,000 gallons of water per year.

Tips:

Older toilets use between 3.5 and 7 gallons of water per flush. By switching to a newer water-efficient toilet you can use 30 to 80 percent less water.

Older washing machines use between 27 and 54 gallons of water per load. Today's standard machines use 23 gallons per load. By switching to a newer, energy- and water-conserving model (front-loading or top-loading, non-agitator ones), you can use less than 15 gallons per load.

Not rinsing dishes prior to loading the dishwasher could save up to 10 gallons per load.
